JOSEPH G. LOCKI-IART, OF ATTICA, KANSAS.

LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Nov. 7, rate.

Application filed April 4, 1916. Serial No. 88,862.

To all whom it may concern:

Be it-known that I, JOSEPH C. Loom-mar, acitizen of the United States,residing at Attica, in the county of Harper and State of Kansas, haveinvented certain new and useful Improvements in Liquid-Fuel Burners; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in hydro-carbonburners and it has for its object to provide a burner of this characterwhich will preheat the fuel to the proper degree to form a gas which,when introduced into the mixing chamber together with the proper amountof air, will produce a perfect combustion, thus eliminating all smoke,such as is found in burners of the ordinary type.

To these ends and to such others as the invention may pertain, the sameconsists in the peculiar arrangement, combination and adaptation ofparts, all as will be more fully hereinafter described, shown in theaccompanying drawings and then specifi cally defined in the appendedclaims.

My invention is illustrated in the accompanying drawings, in which:

Figure l is a side elevation, partly in section, of my improved burner,and Fig. 2 is a bottom plan view, the pan being removed.

Reference now being had to the details of the drawings by letter, Arepresents the burner having a top plate A which is provided with adownwardly extending flange A having openings A therein, which begin atthe lower edge of said flange and terminate about half way between saidedge and the under side of the top plate A, and the space within theburner between the upper ends of the slots A and top plate A forms afuel preheating chamber A. A pan P surrounds the lower edge of theflange A and serves as a bottom or flash pan.

A fuel supply pipe B provided with a controlling valve B is passedthrough the flange A and is coiled as at 13 within the upper part of thechamber A and is then passed out through said flange A and downward, andcoiled as at 13 about the outside of the flange A at a point aboutmidway the height of the slots A as shown in Fig. 1 of the drawings.Said pipe projects a short distance from the burner and is bent backupon itself to form a nozzle B which projects into a mixing nipple Csecured to the flange A the opening through the nipple C communicatingwith the interior of the burner to permit of free passage of air andgas, said gas being c011- trolled by a suitable valve C.

In operation, a small quantity of fuel is ignited in the flash pan whichwill heat the burner and heating chamber A. The fuel within the coil Bwill be preheated and converted into gas which will pass through thecoil B which is in direct contact with the flame from the slots A whichwill further heat the said gas which is then directed into and throughthe mixing nipple C to the interior of the burner. It will thus be seenthat by regulating the fuel supply valve B and the gas valve C a perfectcombustion may be obtained.

l/Vhat I claim to be new is 1. A hydro-carbon burner comprising a platehaving a depending flange with openings leading from the lower edge ofthe flange and terminating short of the lower side of the plate, anipple mounted upon the flange and communicating with the spacesurrounded by the flange at a point between the ends of the openings,and a pipe passing through the flange at a point above the openings andcoiled within the flange and passing out of the same and surrounding theflange between the ends of the openings and having its discharge endalined with the nipple.

2. A hydro-carbon burner comprising a plate having a flange dependingtherefrom and provided with openings leading in from its lower edge andterminating short of the plate, a pipe passing through the flange andcoiled within the same and extending out through the flange and downalong the outer surface thereof and passing around the flange in a planebetween the ends of the openings and having a discharge end disposedtoward the flange and spaced from the same, and a nipple mounted uponthe flange and communieating ,with the interior thereof and alined withthe discharge end of the pipe.

3. A hydro-carbon burner comprising a plate having a depending flange, anipple JOSEPH o'. LOGKHART.

mounted upon the flange and communieating With the interior thereof, anda pipe passing through the flange and coiled therein, then passingthrough the flange and coiled about the same below the nipple and havinga discharge end alined With the nipple.
